All, Loading data into GNU R fails on my dataset: *> gretldata <- read.table("/home/robin/gretl/Rdata.tmp", header=TRUE) Error in read.table("/home/robin/gretl/Rdata.tmp", header = TRUE) : duplicate 'row.names' are not allowed* "Row names" are actually the year (which has duplicates as each records represents a month). To load the data successfully, I have to do: *> gretldata <- read.table("/home/robin/gretl/Rdata.tmp", header=TRUE, row.names=NULL)* Perhaps gretl could test for this before attempting to load the data into R?
